Description
With superior materials and a great design, the MAXX MODEL CNC Aluminium PRO HOP-Up Chamber for M4/AR-15 AEGs is sure to enhance your rifle's performance, accuracy, and consistency. It is constructed from CNC aluminium, one of the highest quality materials used in Airsoft.
It has an aluminium rotary adjustment wheel, which can be finely tuned and adjusted for various weights of BB, holding its setting far more effectively in the long run than the older gear adjuster design. It allows users to enhance the range and accuracy performance of their M4/AR-15 AEGs and other AEGs that utilise the Tokyo Marui or the ICS M4 HOP-up chamber design (please select the correct option for your platform).
The set includes all the parts you will need to complete the unit, except the HOP-up rubber and outer barrel. A nice perk of this HOP unit is its inclusion of the HOP-up lever, which can be used with the included 4mm Nub to perform best with R-HOP and standard-HOP, which keeps your BBs shooting accurately and consistently every shot.
Other HOP-up enhancements include CNC brass side wings, which help slide smoothly into outer barrel slots. The advanced CNC Delrin locking C-clip holds the inner barrel tightly in place to prevent wobbling and twisting. It also has a specially designed BB latching system that prevents excess BBs from dropping on the floor when reloading.
If you're serious about upgrading your AEG, the MAXX MODEL CNC Aluminium PRO HOP-Up Chamber for M4/AR-15 AEGs is an excellent choice. This incredible upgrade part is made from high-quality materials and will provide your Airsoft rifle with insane accuracy and consistency. Get yours now and dominate the battlefield!

Parts Fitting
Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff.
Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.
We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!
Unique Parts
Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.
Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.
If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
